    摘要: Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca 2+ , Mg 2+ , Ba 2+ , Al 3+ , Fe 2+ , Fe 3+ , etc . ). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.

    摘要: Methods are described for activating a glass fiber or flake to participate in polymerizing a resin. The methods may include sizing the glass fiber or flake with a sizing composition that includes a solution containing a polymerization initiator, and activating the polymerization initiator by forming a free radical moiety on the polymerization initiator that can initiate the polymerization of the resin. Additional methods of making a glass reinforced composite are described. The methods may include sizing glass fibers or flakes with a sizing composition that includes a solution containing a polymerization initiator, forming a free radical moiety on the polymerization initiator to make activated glass fibers or flakes, and contacting the activated glass fibers or flakes with a polymer resin. The activated glass fibers or flakes initiate the polymerization of the resin around the glass fibers or flakes to form the glass reinforced composite.

    摘要: Methods of making a fiber-reinforced composite are described. The methods may include applying a sizing composition to a plurality of fibers to make sized fibers, where the sizing composition may include at least one of a curing agent or an accelerator for a resin composition. The sized fibers may be contacted with the resin composition to form a resin-fiber amalgam, where the resin composition includes 50 wt.% or less of a total amount of the curing agent and the accelerator that is also present on the sized fibers. The resin-fiber amalgam may then be cured to form the fiber-reinforced composite.

    摘要: A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized. Improved long-fiber thermoplastics also may be formed to advantage.
